"Everything went as explained, diagramed, and promised by our System Design Specialist, Mr. Nicolas Hruska. We initially contacted just the top two Foundation Repair Experts listed on Angie's List because we can't afford to have our home repaired by anyone who lacks the proper credentials, staff, tools, training, techniques, supplies, 25 year transferrable warranty, and the hands on experience to deliver all services as promised. We are extremely pleased with the final results to take back our homes basement from poor workmanship done by the original builder and owner of our home back in 1979 We purchased the home in 2001 and unknown to us the foundation had been placed on top of clay based sub-soil which was an acceptable building practice back in 1979. Today's building codes prohibit this careless and costly practice of home site preparation for the homeowner. A word to the wise, do your home work first and then protect the biggest asset that most Americans have, their home. Respectfully, Kenny L. Hutcheson, CMSgt, USAF/USN, Ret. Indianola, Iowa"

Basement Waterproofing questions, answered by experts

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.
